All three eyasses were sleeping on the north ledge of the tower when I arrived. Once was so asleep, it was barely visible. There was lots of flapping and jumping around which was enjoyable. I suspect there was also a feeding, but I think it took place in the middle of the tower out of sight.
One of the eyasses looks close to fledging. I would like to see his tail grow in a bit more, but the bird could leave the nest very soon.
